:NON-REFILJLABLE BOTTLE.

- Specification of Letters Patent.

Patented Feb. 29', 1916.

Application filed April 14, 1915. Serial No. 21,262.

To all whom it may concern:

Be it known that 1, MICHAEL H. VVHALEN,

a citizen of the United States, residing at New York, county and State of New York, have invented certain new and useful Tmprovements in Non-Refillable Bottles, of which the following is a full, clear, and exact specification.

This invention relates to bottles and especially to the type generally known as nonrefillable bottles, in which means is provided for preventing liquid from entering the bottle but which does not interfere with the original contents of the bottle being discharged.

The object of the invention is to simplify the construction of bottles of this kind as heretofore made, and to facilitate the discharge of the original contents of the bottle while at the same time rendering it more difiicult to refill the bottle.

Other objects will appear as .tion proceeds.

The invention will be first hereinafter described'in connection with the accompanying drawings, which constitute apart of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views: Figure 1 is a central the descripvertical section through the upper part of a bottle, including the neck and valve mechanism constructed substantially in accordance with this invention. Fig. 2 is a cross section on the line IIII of Fig. 1, looking upward. Fig. 3 is a detailed side view of the valve member. Fig. 4 is a bottom end view thereof. and Fig. 5 is a central vertical section of the upper end portion of the bottle neck inverted, showing the position of the valve when the original contents of the bottle are being discharged.

- The neck 2 of the bottle 1 is screw threaded externally and preferably provided with a smooth straight bore. the neck is reduced, as at 3, to fit a groove formed in the head 6 of a valve member l, within a depending peripheral flange 7 on said head 6. The shank of the valve memher, which fits loosely in the bore of the bottle neck, is provided with longitudinal grooves 5 extending from its lower extremity up to the under surface of the head, said The upper end of I grooves terminating at the top preferably i on a level with the lower edge of the flange 7. The groovein the head 6 may be fitted with a washer or gasket 8 to insure against leakage.

A permanent cap 9 is screwed upon the bottle neck and secured in any suitable manner. This permanent cap is provided with a chamber slightly larger in diameter than the head 6 of thevalve and extending well above said valve when in closed posi-I T tion. The top 10-of the cap 9 may be arched, as shown, and is provided with a central opening 11, the roof or inner surface of the chamber in the cap being dome-shaped, as at 12L v her are "tovided with grooves 13 which extend continuously up the walls from the top of the screw threads and radially along the roof to the discharge opening 11, said grooves converging from allsides to said opening, as best illustrated in Fig. 2.

The permanent cap 9 is screw threaded externally to receive the removable cap 1& which is imperforate and is designed to close the discharge opening 11 in said permanent cap. lVhen the cap 14 is removed and the bottle inverted, as shown in Fig. 5, the valve will move away from the end .3 of the bottle neck and permit the contents of the bottle to flow out through the grooves 5 in the valve stem, around the head-of the valve through the grooves 13 in the walls and roof of the chamber in the permanent cap 9, and the discharge opening 11 in the top of said cap. \Vhen the bottle is in an upright positiomas it must be when an at tempt is made to refill it, the valve will be seated by gravity and the groove in the head of the valve fitting over thereducedend portion 3 of the bottle neck will effectively prevent any liquid which may be poured into the chamber in the permanent cap from entering the bottle. When the cap 14: is screwed on, air is compressed in the chamber of the permanent cap above the head of ,the .valve and forces said valve head down duced end 3 of the bottle neck, it being understood that thepermanent cap fits with an air tight connection upon the bottle neck. In actual practice, it has been found that the valve becomes so firmly seated in this way that it is necessary to give the bottle a sharp rap on the bottom when inverted in order to unseat said valve.

The walls and roof of the chamso that the gasket 8 closely engages the reing a discharge opening 7 I grooves extending up the inner Wall Having thus described my invention, What I claim as new and desire to secure by LettersPatent of the United States is 1. The combination with a bottle neck having a reduced end of constant diameter, of a valve having a stem extendinginto the bore of the bottle neck, and a head having a groove to fit said reduced end portion of the neclg tliere being a short flange on the head of the valve around the groove, and a permanent cap on the bottle neck having a chamber extending Well above the head of the valve when the latter is in closed position, the distance between the head of the valve and the top of the permanent cap, in "this position, being greater than the length of the depending flange around the groove in said head, whereby said flange will beentirely removed from and spaced well away from the reduced. end portion of the neck when the bottleneck is inverted and the valve is in open position, said cap havin the center'olt' its top and of said chamber and radially. across the roof thereof to the' discharge opening.

2. The combination with a bottle neck having a reduced end, of a valve having a stem extending into.the bore of the bottle neck and having longitudinal grooves therein, and a head having a groove to fit said reduced end portion of the neck, and a peris in closed' position,

manent cap on the bottle neck having a chamber extending Well above the head of the valve when the latter is in closed position, said cap having a dome-shaped top with a discharge opening in the center thereof and grooves extending up the,inner wall of said chamber and radially across the roof thereof to the discharge opening. v

3. The combination with a bottle neck having a reduced end, of a valve having a stem extending into-the bore of the bottle neck, and a head having a groove to fit said reduced end portion of the neck, a gasket insaidgroove to engage the reduced end of the bottle neck, a permanent cap on the bottle neck having a chamber extending well abox e the head of the valve when the latter said cap having a domeshap'ed top With a discharge opening in the center thereof and grooves extending up the inner wall of said chamber and radially across the roof thereof to the discharge opening, and a removable cap also havinga dome-sl1aped top to fit over said discharge opening and compress air in the chamber of the permanent cap above the valve head for forcing said valve head firmly down with the gasket making close connection with the reduced end of the bottle neck;

In testimony whereof I have signed my name to this specification.
